As of the end of January 2021, 36 cases of Immune thrombocytopenic purpura (ITP) were reported to the Vaccine Adverse Event Reporting System by the United States government (VAERS). Vaccinations from both Pfizer-BioNTech and Moderna have been involved in the incidents; these are the only two vaccines currently authorised for use in the United States.

It’s too soon to tell if these occurrences of ITP coincided with COVID-19 vaccinations. It is also unclear if immunisation exacerbated already undiagnosed ITP or caused it.
Some haematologist experts in ITP have observed that they assume the vaccine played a role in the start of ITP, particularly considering that viral infections can cause ITP, and given that comparable reactions have happened after pneumococcal, MMR, and other immunizations. However, even if a correlation exists, it’s probably very slight and these instances would be the exception rather than the rule. They may also be the result of a propensity to ITP that is undetected before the commencement of the disorder, especially as it’s possible to have low platelet count without symptoms.
More cases are likely to be needed to better understand any association between the vaccines and ITP and to establish a causal link, if there is one, due to the low number of cases. Both Pfizer and Moderna have issued statements saying they will keep gathering and reviewing public safety data despite the lack of a definitive causal link between their vaccine and any reported adverse events.
Platelet deficiency is the hallmark of the blood condition known as immune thrombocytopenic purpura (ITP). A reduction in platelet count can result in easy or heavy bruising, bleeding from the gums or nose, and internal bleeding. Bleeding into the brain is a rare but potentially fatal consequence of ITP.
Roughly 0.01% of the adult population has ITP. Thrombocytopenia develops when the body’s immune system mistakenly assaults platelets or the cells that make platelets. In some cases, for example, after a viral sickness, the immune system may begin fighting platelets or the cells that generate them, and this can remain for months or even become chronic and persist for years for unknown reasons. thanks for reading our article A Few Covid Vaccine Recipients Developed a Rare Blood Disorder.
